Where are these monitors, that mean font hinting can be tossed aside? You'd think 300dpi screens were absolutely everywhere, and that only people still using 100dpi monstrosities were dinosaurs, sticks-in-the-mud, and your technophobic grandmother - all easily ignored! But that appears to be not the case. The majority of screens (probably all of them, pretty much, going by surface area...) seem to still be at the 100-150dpi resolution. Worse, the higher-DPI screens are on things like laptops, phones and tablets - all devices that have a limit on how far away from your eyes you can hold them! End result: grid still very much in evidence. People are so keen to do away with the very idea of the pixel grid, and just pretend it doesn't exist, but the technology to display the result is just not there yet! Are we going to have to put up with even more years of blurry fonts and coloured fringes, just so that people can pretend the future is here, when it blatantly is not?
